Cause of this behaviour are changes in https://bugs.chromium.org/p/chromium/issues/detail?id=176106.
After url fixup, the first part of input "dtkjnhtyf;th" before ';' is treated like valid url scheme and search provider does not send request for suggest for schemes other than http/https/ftp. This check is implemented in SearchProvider::IsQueryPotentionallyPrivate.

One of the possible solution would be to treat only "http;", "https;", "ftp;" as valid schemes variants in SegmentURL function in url_fixer.cc.
Other would be to change logic of search provider. Yet, from comments in search provider it looks like it does not send suggest requests with non standard schemes to prevent password/usernames leakage.
  // Next we check the scheme.  If this is UNKNOWN/URL with a scheme that isn't
  // http/https/ftp, we shouldn't send it.  Sending things like file: and data:
  // is both a waste of time and a disclosure of potentially private, local
  // data.  Other "schemes" may actually be usernames, and we don't want to send
  // passwords.  If the scheme is OK, we still need to check other cases below.

There could be other solutions as well. WDYT?

We definitely can't change the search provider behavior.  It needs to be as conservative as it is today.

I think changing fixup to only convert ; -> : for known schemes would be OK.

Change semicolon replace logic in url_fixer

This change adds additional check to url_fixer logic while trying to
fix user input. New implementation tries to change ';' to ':'in
SegmentURLInternal only for known url schemes.
